The Problem Abstract In our view, coffee waste is all the coffee ground that did not pour the perfect coffee shot. On average, coffee waste can account for up to 16% of total coffee consumption resulting in a loss of income . Waste during the charge of the coffee portafilter All the coffee grinders on the market generate coffee ground spillage when loading the coffee into the portafilter. The problem is more accentuated in the fresh on demand grinders style, especially when a high coffee dosage is required. Slingshot features a sealed distribution chamber which accurately delivers the ground coffee to the portafilter with no loss of coffee. ≈5% WASTE Waste for calibration In the traditional doser grinder types, the coffee chamber can hold over 300 grams of pre-ground coffee. When the Barista needs to re-adjust the grinding, “calibration”, all the coffee already ground will be wasted. The same applies in the fresh on demand style grinders, where any adjustment of the grinding size, the Barista will need to estimate a new grinding time to maintain the correct dosage. Most of the time this will result in coffees being wasted. The Slingshot’s unique dosing system works on the volume of coffee delivered in the portafilter. the daily adjustment of the grind settings won’t influence the dose provided.Our system minimises the coffee waste during the calibration. ≈6% WASTE Waste for “odd number” coffee What is the odd number coffee? Is the coffee wasted by using only the double portafilter due to the poor performance of the single portafilter. If the request is only for 1, 3 , 5 ..coffees, probably one coffee always gets wasted in the drip tray.

difference that time setting is done automatically

Fresh on demand grinder weight based Weight-based grinders are the latest hype in the market. There are two types of weight-based grinders: Live weight,where an electronic scale continuously monitors the coffee dosage delivered. Post grinding weight,where an electronic scale weighs the coffee dosage at the end.The post grinding weight system is still a time based grinder with the difference that time setting is done automatically by an algorithm based on the weight of last coffee dosage. It is undoubtedly an improvement when compared to existing fresh on-demand grinders, but they still carry problems such as coffee wastage, speed and the high purchase cost.

Fresh on demand grinders Fresh on demand times based grinders are very erratic. Many variables can affect the dosage delivered and the grinding quality. Every time there is a new grinder setting, the Barista will need to estimate a new grinding time with the risk of entering in a loop of hit and miss adjustments. Fresh on demand grinders may perform well in the hands of a skilled Barista, the reality is that many venues serving coffee don’t have a dedicated barista but rather a number of personnel filling the role with minimal training. This creates the need for a foolproof Slingshot coffee grinder which doesn’t require expert knowledge to operate.
